HI !I need help for simple thing that I can not make work, and do not found any (right words?) solution with search.

I have Tmemo with some text. Say it has "Hello".I paint word "world" from another App and drag and drop it over Tmemo.

Tmemo will then have text "Helloworld".

But I want that dropping erases "hello" and leaves just "world".I have tried several ways: OnDrop (Tmemo.Clear)OnMouseOver(select all, but if drag is on no selection is made, otherwise yes)ONMouseUP .... and so on.

Hi!Seems that that nobody does know solution for this! Over 200 times read, with no suggestions at all.

One way to go around this is to paint text in other program, NOT drag it, place cursor over TMemo and press mouse wheel button.In that way at least my Fedora26/LXDE erases the old text and drops the painted text in TMemo.
